Apart from, as pointed out, turn my lights off, I also use a program called F.lux to warm the colours of my monitor at night. I sleep incredibly well.

Being around those lights around the house if i went into the bathroom or something before sleeping would just wake me up, i can't stand them. I use flux too, i can hardly keep standard yellow lighting on around the house other than just dim lamps and such. Nevermind one that mimics straight up daylight.

We need new lights in our house, currently the bathroom has a dodgy, almost no luminescence, special ring shaped bulb. The bad thing is that it's useless during the day. The good part is your eyes don't explode when you need to piss in the early hours

My physics teacher a while ago told us that we actually see better under yellow light,. The details were quite amusing but I forgot all of that
I prefer white lights though.

This is because the human eyes have a limited bandwidth of frequencies they can see, this starts at red and ends with purple. Things like infra-red and ultra-violet are outside the spectrum of visual light because our eyes simply didn't evolve to be able to see it. Right in the middle of the visual spectrum (which as I said ranges from red to purple, just like the rainbow) is green and yellow.
Because of this we register yellow and green much better than say red or blue or white for that matter.
